Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a construction method for a suspended spherical restaurant. Background Technology

[0002] With the rapid development of modern architectural decoration technology, interior space design is evolving towards diversification, artistry, and high technology. Irregularly shaped space decoration has broken through traditional boundaries, gradually developing towards innovative forms such as suspended and panoramic designs. Against this backdrop, the themed spherical restaurant, as a representative work of architectural decoration art, faces unprecedented technical challenges in its construction and installation: achieving a visually striking suspended effect while ensuring structural safety and stability; meeting the precise construction requirements of complex curved surfaces while achieving a perfect unity of functionality and artistry.

[0003] Traditional spherical restaurant installation techniques suffer from several technical drawbacks, severely restricting the project's construction quality, safety, and artistic expression. First, structural stability is compromised: reliance on a single load-bearing point results in insufficient wind load resistance and inadequate precision in dynamic balance adjustment. Second, installation accuracy is uncontrolled: traditional total station positioning cannot meet the three-dimensional coordinate control requirements of irregular curved surfaces, and welding thermal deformation leads to excessive radial runout deviations. Finally, construction efficiency is low: the high-altitude assembly method extends the construction period by 35% (compared to modular installation), on-site welding accounts for over 60% of the work, generating numerous process interruptions, and the average time for lifting and positioning curved surfaces is 3.2 times that of conventional flat surfaces. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction method for a suspended spherical restaurant, which solves the problems of poor structural stability, difficulty in controlling construction and installation accuracy, and low construction efficiency of existing spherical restaurants.

[0006] The present invention discloses a construction method for a suspended spherical restaurant. By combining factory prefabrication with on-site hoisting, the installation cycle of the main structure is shortened, construction efficiency is improved, project risks are reduced, and construction quality and safety are guaranteed.

[0009] A further improvement of the construction method of the suspended spherical restaurant of the present invention is that the construction of the supporting steel structure at the outer edge of the floor slab includes: providing a corbel member and connecting the corbel member to a pre-embedded plate in the floor slab.

[0010] A further improvement of the construction method of the suspended spherical restaurant of the present invention is that the installation of the lower hemisphere stabilizing ring structure above the supporting steel structure includes: setting multiple curved cantilever components on the outside of the supporting steel structure to form a support; and erecting a lower hemisphere stabilizing ring beam above the support.

[0011] A further improvement of the construction method of the suspended spherical restaurant of the present invention is that, before hoisting the upper hemisphere stabilizing ring structure above the plurality of lifting devices according to the lower hemisphere stabilizing ring structure, the method includes: installing a telescopic guardrail between the lower hemisphere stabilizing ring structure and the upper hemisphere stabilizing ring structure.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1 and Figure 2 , Figure 1 The diagram shows a construction method for a suspended spherical restaurant according to the present invention. Figure 2 A structural schematic diagram of the suspended spherical restaurant of the present invention is shown. The present invention provides a construction method for a suspended spherical restaurant, comprising the following steps: Execution step S110: Construct supporting steel structure 5 at the outer edge of floor slab 6.

[0031] In this process, a full-span scaffold is erected on the base plate of the construction area and used after the scaffold has passed inspection. A supporting steel structure 5 is constructed at the outer edge of the floor slab 6 to form a support base for supporting the spherical restaurant. Then, step S120 is executed.

[0032] Execution step S120: Install the lower hemispherical stabilizing ring structure 1 above the supporting steel structure 5.

[0033] Among them, the lower hemisphere stabilizing ring structure 1 is the stable basic structure of the spherical restaurant. The floor structure can be constructed based on the lower hemisphere stabilizing ring structure 1, the supporting steel structure 5 and the floor slab 6. Then, step S130 is executed.

[0034] Execution step S130: Provide multiple lifting devices 3, and arrange the multiple lifting devices 3 at intervals on the lower hemisphere stabilizing ring structure 1.

[0035] Among them, the upper end of the lower hemisphere stabilizing ring structure 1 is provided with a reserved hole, which allows the jacking and guide rod equipment to be quickly installed on the upper end of the lower hemisphere stabilizing ring structure 1 through the reserved hole on site, thus improving construction efficiency. Then, step S140 is executed.

[0036] Step S140: Based on the lower hemisphere stabilizing ring structure 1, the upper hemisphere stabilizing ring structure 2 is hoisted above the multiple lifting devices 3.

[0037] Among them, the lower hemisphere stabilizing ring structure 1 and the upper hemisphere stabilizing ring structure 2 form a stable ring. The balance ring provides strong structural support for the main structure of the upper hemisphere, ensuring that the upper hemisphere operates stably under the condition of a large total mass. Then, step S150 is executed.

[0038] Step S150: Install the first surface layer on the lower hemisphere stabilizing ring structure 1.

[0039] The installation method of the first surface layer will be described in detail below and will not be repeated here. Next, step S160 will be performed.

[0040] Step S160: Install the second surface layer on the upper hemisphere stabilizing ring structure 2.

[0041] The installation method of the second surface layer will be described in detail below, and will not be repeated here. Next, step S170 will be performed.

[0042] Execution step S170: Install the gate between the lower hemisphere stabilizing ring structure 1 and the upper hemisphere stabilizing ring structure 2.

[0043] The door can be an aluminum sliding door or a glass folding door, depending on the requirements, and no specific restrictions are imposed here.

[0044] In this embodiment, a level is used to measure the elevation and position of the steel structure of each spherical restaurant. The measurement and layout method is as follows: Based on the elevation point of the civil engineering structure handover building (known elevation point), the level is stably set up at an equidistant position between the backsight point A (known elevation point) and the frontsight point B (the point to be measured). After accurate data is obtained, the corresponding positions are marked, and the marked points are fully covered with pine oil. At least two elevation points are marked for each sphere.

[0045] See Figure 3 This diagram illustrates the process before step S110 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, which includes the following steps before step S110: Step S1101: Use BIM software to digitally model the spherical restaurant and analyze the spherical cabin model.

[0046] Based on the design requirements of the spherical restaurant, a 3D digital model was used to create a digital model of the cabin. Using BIM software, Rhino+Grasshopper was employed for digital modeling, and the spherical cabin model was analyzed in detail, enabling rapid model analysis.

[0047] See Figure 4 This diagram illustrates another process flow before step S110 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, which further includes the following steps before performing step S110: Step S1102: Disassemble the various components of the spherical restaurant into a modular assembly and input them into the spherical cabin model.

[0048] Among these methods, the collision between the internal steel frame and the surface material was examined using a spherical cabin model.

[0049] In this embodiment, the various components of the sphere are disassembled into an assembly form, and the measured elevation points are recorded in a 3D model. Then, the internal steel frame of the sphere is modeled based on these elevation points, and collisions with the surface material are checked. The data from the modeling is used to export a processing order for each component, which is then processed in the factory. After processing, the components are installed and adjusted on-site according to the measurements and model dimensions.

[0050] See Figure 5 The diagram shows a flowchart of step S110 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, step S110 including: Execution step S111: Provide the corbel component and connect the corbel component to the embedded plate in the floor slab 6.

[0051] Among them, the bracket components are welded on the embedded plate, and the welds are fully coated with anti-rust paint after passing the inspection.

[0052] In this embodiment, a pre-embedded plate is embedded in the floor slab 6 structure in advance, and one end of the pre-embedded plate is exposed to facilitate positioning and connection during subsequent construction.

[0053] See Figure 6 The diagram shows a flow chart of step S120 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, step S120 including: Step S121: Multiple curved cantilever components 11 are set on the outside of the supporting steel structure 5 to form a support.

[0054] The vertical transport of the curved cantilever component 11 can be carried out using an indoor elevator or a small crane to the floor slab 6, depending on the actual construction needs. No specific restrictions are imposed here. Next, step S122 is executed.

[0055] Execution step S122: Erect the lower hemispherical stabilizing ring beam 12 above the support.

[0056] The curved cantilever component 11 can be spliced ​​using I-beams. In this embodiment, the curved cantilever component 11 is spliced ​​from four I-beams.

[0057] In other embodiments, the curved cantilever component 11 can be prefabricated in a factory and welded together on site. Construction workers must wear safety belts throughout the entire operation on the full-span scaffolding, and a dedicated safety officer must supervise the process to ensure construction safety.

[0058] See Figure 7 and Figure 8 , Figure 7 This shows a flowchart before step S140 of the present invention. Figure 8 A structural schematic diagram of the telescopic guardrail of the present invention is shown. The present invention provides a construction method for a suspended spherical restaurant, which includes the following steps before performing step S140: Step S1401: Install telescopic guardrail 4 between the lower hemisphere stabilizing ring structure 1 and the upper hemisphere stabilizing ring structure 2.

[0059] The telescopic guardrail 4, in conjunction with the lifting device 3, can adjust the height of the upper hemisphere stabilizing ring structure 2. The telescopic guardrail 4 can provide safety when the space is opened during the rise of the upper hemisphere stabilizing ring structure 2. To ensure the aesthetics of the guardrail, when the guardrail is raised, the main body of the guardrail is located in the middle of the upper and lower hemispheres. When the guardrail is lowered, it is flush with the internal space platform.

[0060] See Figure 9 This diagram illustrates the process before step S150 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, which includes the following steps before step S150: Execution step S1501: Install functional units and fire protection units by wiring on the lower hemisphere stabilization ring structure 1 and the upper hemisphere stabilization ring structure 2.

[0061] The functional unit construction involves integrating the pipelines required for the spherical restaurant, as well as installing the ceiling, floor, tables, and chairs on the lower hemisphere stabilization ring structure 1 and the upper hemisphere stabilization ring structure 2. The fire protection unit construction involves installing fire sprinklers, smoke detectors, APs, broadcasting systems, lighting fixtures, and exhaust fans within the suspended ceiling of the upper hemisphere stabilization ring structure 2.

[0062] In this embodiment, the pipelines are integrated through the vertical frame of the upper hemispherical stabilizing ring structure 2. For example, for the pre-embedding of sprinkler pipes, the fire protection unit needs to process the vertical frame according to its arc shape and dimensions, and then provide the vertical frame to the factory for simultaneous processing into a whole. Threaded connectors are reserved at both ends to facilitate the on-site organization of the main and branch pipes at both ends. Most other pipelines are 20mm diameter galvanized conduits, and the construction steps are the same as for fire protection pipes.

[0063] See Figure 10 The diagram shows a flowchart of step S150 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, step S150 including: Step S151: Assemble aluminum plate units on the lower hemisphere stabilizing ring structure 1.

[0064] The aluminum plate unit is designed as an arc-shaped plate, and is assembled around the lower hemisphere stabilizing ring structure 1 to form an outer shell. The outer wall of the aluminum plate unit can be painted, and different colors can be selected according to requirements. The size of the aluminum plate unit is determined according to actual construction needs and is not specifically limited here.

[0065] See Figure 11 The diagram shows a flowchart of step S160 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, step S160 including: Step S161: Assemble the glass unit on the upper hemisphere stabilizing ring structure 2.

[0066] The glass units are made of hyperbolic ultra-clear tempered glass. The dimensions of the glass units are determined based on actual construction needs and are not specifically limited here.

[0067] See Figure 12 This illustrates another flowchart of step S160 of the present invention. The present invention provides a construction method for a suspended spherical restaurant, and step S160 further includes: Perform step S162: Apply a heat insulation film to the inner wall of the glass unit.

[0068] Among them, 3M Crystal Platinum insulation film is applied to the glass curtain wall on the side closest to the interior, which has the effect of heat insulation and heat preservation, maintaining the stable temperature inside the spherical restaurant.

[0069] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
